<p>In an electric DC are furnace having a vessel with a jacket and a bottom, electrodes are arranged in the bottom which electrodes are comprised of wear and consumable element, penetrating a refractory lining of the vessel for engagement with molten metal in the interior of the vessel. The consumable element being provided with an axial blind bore including a copper sleeve is inserted which sleeve, in turn, receives a heated tubular element for the conduction of cooling medium; a graphite layer is provided in the fireproof lining and extends parallel to the jacket, this layer at least partially embracing and enveloping the consumable electrode element at least to some extent, as far as the length extension of the bottom electrode is concerned.</p> |
